S1·E22 Going to the Dogs

Mike takes Abby to buy a dog, Abby desperately wants a pet but Kate is completely against the idea. Kate cannot deal with the dog that Mike gets her and to calm it down she decides to buy some strong dog tranquilizers. This works, but when Mike takes the dog for a walk he takes a fancy to the meatballs in Kate's kitchen. Unknown to him the meatballs are laced with the tranquilizers and he is soon beginning to feel rather drowsy, just at the time when he and Kate are having a meeting with Abby's teacher.
